Before Cycling

Blood sugar levels are restored from the body's glycogen reserve which is made from carbohydrates. To keep glycogen levels high carb load the night before with a meal based on something starchy like pasta or rice. Porridge makes an excellent breakfast as the oats provide slow release carbs. As an alternative SIS make PSP22 which is a carbohydrate solution that can be drunk at any time to top up energy levels. Drinking extra water in the 2 hours before a ride can help to maintain hydration levels.

During A Ride

On a hot day a lot of electrolytes (salts) are lost through perspiration, and this can reduce performance and is one of the factors that causes cramp. To combat this SIS make their GO drink which contains a mix of electrolytes and carbohydrates. GO is also available in gel form, which is handy to give a boost towards the end of a ride. Because of the electrolytes GO drinks should not be made too concentrated, so PSP or energy bars are useful on longer rides to top up carbohydrate levels.

Drinking enough water is essential, and if you wait until you feel thirsty it's too late. Up to a litre of fluid is required every hour in hot weather, so always take 2 large water bottles or a hydration pack on long rides.

After A Ride

This is the bit that most riders forget about, and it is the leading cause of aches and pains the next day! A lot of cyclists eat and drink properly before and during a ride, then afterwards just put their feet up. Exercise damages muscles, which then recover and get stronger after training. However, to do this they need protein and they need it fast. SIS have created Rego, a drink containing protein, vitamins and a little carbohydrate, which should be taken within 30 minutes of the end of the ride. Try it and feel the difference for yourself the next day.

Fluids are important, but avoid alcohol. Fatty foods are also a bad idea as they reduce absorption of other nutrients, so try and leave the pie and chips washed down with a beer in the pub until a couple of hours after the ride.
